The world is nothing but an illusion. It emerges all of a sudden. Even as a dream comes into being all of a sudden. Out of nothing it rises.

Against the background of the film screen there appears the world, the life. All the projected pictures of the movie the television the video appears so real while they are being projected. On the screen itself there is nothing. The screen is always the same. The projected pictures come and go.
